Writing the Equation of a Line Using Slope-Intercept Form Chapter 5.1

2
Slope-Intercept Form of a Line y = mx + b. The slope-intercept form of the equation, m is the slope and b is the y-intercept. y = 3x – 4 The slope is 3. The y-intercept is (0, -4). The slope is The y-intercept is Recall that the y-incept is the y-coordinate of the point where the line crosses the y-axis.
